About this study

Patients with low back pain will undergo ultrasound imaging of the lateral abdominal wall to measure resting and contracted thickness of the transversus abdominis muscle. Following the pre-intervention measurement, patients will receive one of two physical therapy interventions (side lying thrust joint manipulation or side lying non-thrust oscillations into slight rotation) which will have been randomly assigned. Immediately after intervention, ultrasound imaging will be repeated on the resting and contracted thickness of the transversus abdominis.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Currently receiving physical therapy treatment for back pain or back pain symptoms
  • 18-70 years of age
  • Able to perform the abdominal drawing in maneuver

Exclusion criteria

  • Presence of a serious pathology
  • Diagnosis of spinal stenosis or symptoms in both lower legs (changes in sensation, muscle weakness)
  • Any history of low back surgery, rheumatoid arthritis, osteoporosis, osteopenia, or ankylosing spondylitis

Primary outcomes

  1. Transversus abdominis thickness change

    Time frame: Baseline to immediately after the intervention (within 5 minutes)

    Measurement of change in thickness from resting to contraction will be compared at baseline (pre-intervention) to immediately following the intervention (post-intervention). The study is looking at the immediate effects so there is no short-term or longer term follow up.

Secondary outcomes

  1. Numeric Pain Rating Scale

    Time frame: Baseline to immediately after the intervention (within 5 minutes)

    Rating of perceived pain will be compared at baseline (pre-intervention) to immediately following the intervention (post-intervention). The study is looking at the immediate effects so there is no short-term or longer term follow up.
